Coffee Gourmet one-cup filter is claimed to produce a superior brew

There's no shortage of companies promising to make you the perfect cup of coffee. Amongst the recent devices Gizmag has covered are the smartphone-connected Arist and Bruvelo, as well as the 4-hour Imperial Proper Coffee Drip. The new Coffee Gourmet filter, however, is reportedly simpler and quicker.

The Coffee Gourmet is designed for producing one cup at a time, and the company promises that it produces a "superior" flavor. The strength of the brew can be altered by exposing more or less of the Coffee Gourmet's filter as required. The device is then filled with the recommended amount of ground coffee and is hooked onto the side of a mug, hanging down inside.

When the advised near-boiling water is poured into the device, it is soaked up by the coffee grinds. The grinds initially block the filter, but as they soak up the water they produce carbon dioxide and start floating to the top. This is said to ensure that no liquid passes through the filter until the coffee has been adequately saturated and has had time to "bloom."

A constant source of fresh, near-boiling water is poured into the Coffee Gourmet until the mug is filled. This ensures that the temperature remains at a constant 95-98º C (203-208º F) and there is enough pressure produced to push the water through the filter. The process takes about 30-40 seconds, which ensures that there is no "over extraction" from the grinds and avoids producing a bitter flavor. This is a common problem with other brewing methods.

A Kickstarter campaign is underway to raise money for the production of the Coffee Gourmet. Individuals can pledge from £10 (about US$16) to receive a device, assuming the campaign reaches its goal and the production process goes to plan.
